You can't re-submit your return if it's been accepted in eFile, and you won't generally file Form 1040-X for an administrative issue such as this.
However, you might consider filing a Form 8821, Tax Information Authorization with the IRS.
This will authorize you to inspect and/or receive your father's confidential information verbally or in writing for the type of tax and the years or periods listed on the form. You don't have to be an individual authorized to practice before the IRS, as you would with a Power of Attorney.
Please see the IRS' Power of Attorney and Other Authorizations page for more information.
